Oil-filled and pressure compensated transistor inverter, which is suitable to be installed on 6,000m class deep submersibles, is being developed, in order to get characteristics of small size, light weight and high efficiency. As the first step of developing this inverter, principal parts as mentioned below which are able to function in the environment of high pressure are just developed and reported in this paper. 1) Large capacity power transistor 260 V, 300A 2) Large capacity electrolytic condenser 160 VAC, 6,800 μF 3) Power diode 260 V, 300A 4) Oil condenser 250 VDC, 1 μF and 115 VAC, 147μF 5) Current transformer, reactor, small capacity diode, and resistor All parts developed are manufactured as trial, and examined under three states of (1) atmospheric pressure in air regarding electrical performances, (2) different pressures up to 938kgf/cm^2 in oil regarding electrical and mechanical performances and (3) cyclic pressure of 1,000 cycles from 0 to 625kgf/cm^2 in oil to prove mainly mechanical durability. As the result of these developments, almost all the parts necessary to assemble the oil-filled inverter system have been obtained, except control circuit which is planned to be installed in pressure proof vessel because of its complexity of being oil-filled and its less capacity. At Present, development of oil-filled and pressure compensated transistor inverter system is in progress as the second step, using the parts developed here.
